Definitions
- the present invention relates to a method of processing binary program files, comprising a step of transferring a binary program file in the form of binary data packets over a communication network between a transmission device of a server platform and a reception device of a client platform, referred to below as a target platform.
- It also relates to a data-processing device which is suitable for receiving binary program files transmitted over a communication network in the form of binary data packets by a transmission device of a server platform.
- a source platform being, for example, a games console
- a target platform being, for example, a digital television receiver-decoder also called “set-top box”, a personal digital assistant or a mobile telephone.
- U.S. Pat. No. 5,819,067 proposes to use a system with two processors for the binary translation and running of a binary program file.
- One processor is dedicated to the binary translation, and the other to running the translated binary program file.
- the first processor starts by translating a first page of the binary program file. It then translates a second page and, during this time, the second processor runs the first page.
- This system hence makes it possible to run the binary program file as it is being translated.
- the binary program file may occupy a large memory space, ranging from a few hundred kilobytes to a few dozens of megabytes. Consequently, the downloading via the communication network may take many minutes, and the user has to wait for a long time until the binary program file is usable.
- the method of processing binary program files is characterized in that it furthermore comprises:
- the present invention makes it possible to start the processing of the binary program file (this processing being, for example, binary translation) as soon as a portion of code has been identified.
- the downloading of the binary program file, on the one hand, and the processing of the binary program file (for example, the binary translation and the running of the binary program file) by the reception device, on the other hand, are carried out according to a pipeline principle.
- the method of processing binary program files consequently makes it possible to process the binary program files more rapidly than the prior art, for the user's greater convenience.
- the present invention also relates to a data processing device which is suitable for receiving binary program files and of implementing the method of processing binary program files, for example in an integrated circuit, with the aid of hardware or software means.
- FIG. 1 represents a communication system for binary program files according to the invention
- FIG. 2 represents a timing diagram of the various steps of the method of processing binary program files according to the invention.
- the present invention relates to a system for communication between a server platform and a target platform, as illustrated in FIG. 1 .
- the target platform is, for example, a digital television receiver-decoder, a personal computer, a personal digital assistant or a mobile telephone.
- Said system is suitable for transferring binary program files from a transmission device NE ( 12 ) of the server ( 10 ) to a reception device ( 14 ) of the target platform ( 18 ), via a communication network ( 13 ).
- the target platform has binary translation means BTU ( 15 ) which are suitable for translating the binary program file ( 11 ) transmitted by the server into a binary program file which can be run on the target platform, that is to say, which is compiled according to the operating system and/or the processor CPU ( 16 ) of said platform.
- the present invention comprises starting the binary translation and running the binary program file which is transferred as soon as possible, without waiting for the end of the transfer of said file.
- the invention is based on the fact that the files are transferred several packets at a time in communication networks which operate according to the TCP/IP protocols (Transmission Control Protocol/Internet Protocol), the two communication protocols which form the foundations of the Internet. Some of the content of a binary program file being transferred is hence available before the transfer of the whole binary program file has been completed.
- the method of processing binary program files according to the invention comprises the three main steps whose implementation as a function of time (t) is illustrated in FIG. 2 .
- the binary translation means BTU ( 15 ) start to process the binary program file as soon as the first data packet sent by the server has arrived.
- the target platform comprises storage means, for example a memory or a hard disk, which are suitable for storing the data packets, and the binary translation means are suitable for reading the content of the storage means periodically, according to a principle which is known to the person skilled in the art.
- the reception device of the target platform according to the invention is suitable for reading the packets as they arrive. Since the file transfer protocol FTP does not require the packets to arrive in the same order as that in which they were sent, the reception device furthermore comprises reordering means which are suitable for reordering the packets into ordered packet groups ( 25 ), the size of these packets depending on the order of arrival of the packets. In order to optimize the method of processing binary program files, the reordering means preferably deliver the smallest possible reordered packet groups. It will, however, be apparent to the person skilled in the art that the packets may also arrive directly in order, for example as in the case of the transfer protocol IPv6. In this case, the role of the reordering means is to ensure that the packets are actually received in order.
- the first packet group comprising the first packet and possibly packets which are immediately subsequent to it and have been stored before it is delivered to the binary translation means BTU ( 15 ).
- Said means can then start the binary translation.
- most binary program files have a data structure whose processing (whatever it may involve) requires a decoding phase which is carried out continuously from the start to the end of the file, the information present at the start of the file describing the rest of the file.
- the ELF, C0FF, IEEE695 or Intel OMF formats may be mentioned.
- Such binary program files are divided into several sections.
- the first section contains general information about the file, such as a magic number for identifying the binary format type, the version and type of the file, its creation dale, or the size of the file. It also contains information about the subsequent sections, for example, the number of sections and their offset from the start of the file.
- the binary translation means are hence suitable for preparing for reception of the rest of the binary program file, in particular by allocating the necessary memory spaces, and of constructing the data structures of said file.
- the subsequent sections contain code and variable data. When other packet groups are received, the binary translation means hence read the content of other sections, and detect portions of code inside these sections. When these portions of code are identified, the binary translation means prepare the data structures which are associated with them.
- the binary translation means includes a static translation unit and a dynamic translation unit. As soon as the start of the code is available, the static translation unit starts a static translation of the portions of code. The dynamic translation unit starts a dynamic translation as soon as an execution starting point has been identified inside the code.
- a third step ( 23 ) the instructions which have been translated are sent to a processor CPU ( 16 ) of the target platform, with a view to running them.
- the running of the binary program file also takes place as said file is being translated.
- Said delay may be due to the fact that the binary translation means are in the process of translating the subsequent set of instructions, or are waiting for portions of code to translate.
- a computer program contained in a programming memory may make the circuit carry out various steps of the method of processing binary program files which has been described above.
- the computer program may also be loaded into the programming memory by reading a data medium, for example, a disk which contains the computer program. The reading may also be carried out via a communication network, for example the Internet network. In this case, a service provider will make the computer program available to those interested.
